When the copper wires here were replaced by fibre optic ones they were taken as far as the nearest poles. Then varying companies called round trying to get customers to have the new system in their homes. I recklessly signed up as my contract with my internet company was due to run out, and they offered a great deal, including a free new line into my house, very, very fast internet and inclusive 24/7 phone calls for less than I was paying. My new wire was connected to the nearest pole, not the same pole I had been connected to before, and a black box installed inside. All done in a morning. They connected my mobile to the wifi, and installed an app on my mobile which I can control the modem with. It all works very well and since then I've added the TVs, HD recorder WiFi printer, etc. When I changed my mobile, I managed to install the app to control the system on my new phone without a problem. My old landline phone plugs into the black box, same number. The only difference being I have to use the area code for local numbers too.
Some of my neighbours have still got their old wires from the pole and there are some new wires which go over to the next cul de sac.
The mobile signal here is also very hit and miss. At home I just tend to use my mobile for internet on the WiFi.
